Asrock P45R2000WiFi RAM CPU Problem

Forum Overclocking : Motherboards Asrock P45R2000WiFi RAM CPU Problem

Word :    Username :           
 

My PC components:
Asrock P4R2000WiFi
CPU - Intel Dual Core E8400 E0 stepping
Sapphire Radeon HD 3870 Ultimate
RAM G.SKill 4GB Kit DDR2 PC2-8000 (F2-8000CL5D-4GBPQ) CL5

I set jumper FSB2 3-4 and FSB3 3-4 like manual for 1600MHz FSB.
Bios and Windows show taht my cpu speed is 3.6GHz
I have testet but during i got bluescreen.
Now Bios and Windows show that my CPU Speed is 3.00Ghz
Bios settings are identically like earlier CPU Frequency Auto - 400MHz
but CPU not apply this settings. I have changed to auto to manual
(with the same speed settings) now Bios show CPU Speed 2.9
and can't recognize properly my RAM. CPU-Z show FSB 1333.3
RAM 444.4 MHz FSB:RAM 3:4....
If I set jumper to default (1-2 1-2) Bios show properly my RAM Frequency
CPU-Z show 533.33MHz. I tryed to set new CPU-frequency with Asrock OC Tuner CPU not aplyed this settings... show all the time 2.99xx for CPU Speed.
It worked before i set FSB to 1600...
Now with OC Tuner i can change ONLY the Ratio (default 9) to slower than CPU applied the changes....
I tryed to re-flash the bios - no results...
Any ideas what have I destroyed ?

Many thanks for responses.

With Best Regards
Adam

Will this be a good build to overclock 2500k to 5.0GHz?

I'm the one that told him that a Silver Arrow will get to 5Ghz, so I'll take the blame...
